Detailed Description
AWD-40 is a variant of seismic source of the “weight drop” type. The striking mass (hammer) is accelerated with the aid of massive stretching springs that are armed by means of an electric winch powered by a car battery (65–180 A/h). The minimum period of operation of the source is 3 s.
The source AWD-40 is mounted on a compact lightweight frame equipped with reliable wheel blocks. The delivery package of the source includes one hammer: 20, 33 or 40 kg. Hammers of another weights can be supplied additionally. The design of device allows hammer’s fast replacing in the field. The source can be used on a rugged terrain. The total weight of the source without battery pack is less than 120 kg. The energy of a single impact reaches 1000 J.
The source can be mounted on a trailer, trunk of a pickup, a four-wheeler or a compact wheel pair (tow bar — four-square).
The set includes:
- Source AWD-40
- Wired control console
- Technical manual
Can be acquired additionally:
- Additional hammer
- Sealed (gel) battery 90 A*h
